•Well-circumscribed, flat lesions that are
noticeable because of their change from normal
•They may be red due to the presence of
lesions or inflammation, or pigmented due to the
Presence of melanin, hemosiderin, and drugs.
Solid lesions raised above the skin
surface that are smaller than 1 cm in
diameter. Papules may be seen in a
wide variety of diseases including
erythema multiforme simplex, rubella,
lupus erythematosus, and sarcoidosis.

cm in diameter; they are large
These lesions are present deep in the

easily moved over them.

abnormal area of the oral mucosa that on
clinical examination appears whiter than the
surrounding tissue and is usually slightly raised
,roughened or of a different texture from
adjacent normal tissue.
Any area of reddened mucosa that may be
smooth and atrophic looking or exhibits a
granular, velvety texture

are usually seen,plaque like lesions are also
seen that cannot be differentiated from

to pharynx and esophagus
•Referred pain in ears, deafness and nasal voice
localized,diffused or lace -like network.
•As disease progresses mucosa becomes stiff and
vertical fibrous bands appear.
In lip-circular bands appear. (Circum rima oris)
In severe involvement of the lip-lips become leathery,
difficult to avert
In palate-bands radiate from the pterygomandibular
raphe to the anterior faucial pillars.
Faucial pillars - thin and short.
•Tonsils- may be pressed between the faucial

bud like or hockey stick
•Tongue-devoid of papillae, stiff with
impaired protrusion in severe cases
•Floor of the mouth-blanched and leathery
•Petechiae seen in 1/5th of cases.
CLINICAL AND FUNCTIONAL STAGING
Haider et al 2000 BJOMS
•Stage 1-faucial bands only
•Stage 2-faucial and buccal bands
•Stage 3-faucial,buccal and labial bands
•A –mouth opening >20mm
•B-mouth opening 11-19 mm
•C-mouth opening < 10 mm
•Decreased serum iron
•Increased total Fe binding capacity
•Decreased total saturation of transferrin
•Decreased total serum iron

GUIDELINES FOR MANAGEMENT
Clinical observation without biopsy is dangerous
Response to hyperkeratotic leukoplakia is
unpredictable,so biopsy to be repeated every 6 –
12 months particularly if the lesion changes in
size or physical characteristics.
Adequate follow up,especially for
nodular,Verrucous forms and leukoplakia at the
floor of the mouth and tongue.
Surgical stripping with graft
Marked changes in the oral microbial flora
Broad spectrum antibiotics
Excessive use of anti microbial mouth rinses.
Xerostomia secondary to anticholinergic agents and
